Description

  The present invention relates to a clean and hygienic sink that is hard to get dirty in a sink in a sink.

  9 and 10 show a conventional kitchen sink 1. As shown in FIG. 9, the conventional sink 1 generally has a drain outlet 3 disposed in the vicinity of the center of the sink 2, and the water after washing ingredients, dishes and the like is collected from the periphery to the center. As shown in FIG. 10, the water is drained from the drain port 3 through the drain pipe 4. The trap portion 5 between the drain port 3 and the upper end of the drain pipe 4 has a perforated waste basket 6 for temporarily storing cooking waste and a perforated lid 7 for covering the top opening of the waste basket 6. The lid 7 is installed so as to maintain a substantially horizontal plane with the bottom surface 2 a of the sink 2.

  However, in the conventional general sink shown in FIG. 9, the drainage port 3 is located near the center of the sink 2 that is the center of the washing place, and the washing place tends to become dirty from the vicinity of the center of the sink 2 to the periphery thereof. In order to temporarily store cooking debris etc. in the waste basket 6, various germs are likely to grow near the drain outlet 3, so if you try to wash food and dishes near the center of the sink 2, There was a problem of lack of hygiene due to the rebounding of water. For this reason, when it is attempted to perform the washing work around the sink 2 while avoiding the vicinity of the drain outlet 3, the space is small and the workability is poor. For this reason, the conventional general sink is not easy to use. Furthermore, in order to improve washing workability, the entire bottom surface 2a of the sink 2 is formed in a flat shape, and if the remaining juice such as a pot is spilled toward the drain outlet 3, the remaining juice will go around the sink 2 as a whole. The entire sink 2 was easily soiled, and in this respect it was not hygienic.

  Further, in the structure in which the drainage port 3 is arranged at the corner of the sink 2 as shown in Patent Document 4, although the washing workability is somewhat improved, the vicinity of the drainage port 3 and the sink 2 as a whole are easily contaminated. It was the same as the sink 1 shown in FIG.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a clean and hygienic sink in which the washing area in the sink is not easily soiled.

  In order to solve the above-mentioned problem, the sink according to claim 1 of the present invention is arranged such that a drainage recess continuing from the bottom surface of the washing zone in the sink is arranged at a side end or corner in the sink, A drainage outlet is provided, and a downward slope is provided on the entire bottom surface of the washing zone toward the drainage recess and on the drainage recess toward the drainage port.

  According to the sink according to claim 1, the water after washing ingredients, tableware, pans, etc. on the bottom surface of the washing zone flows down from the upstream region to the downstream region on the bottom surface of the washing zone, It falls into the drainage recess, passes through the drainage recess, and is drained from the drainage outlet into the drainage pipe. That is, the water discharged from the discharge pipe of the faucet fitting flows like a river on the bottom surface of the washing zone toward the drainage recess at the side edge or corner, and falls into the drainage recess like a waterfall. In the washing zone, there is no drainage port and no lid that closes the drainage port, so the water flows smoothly into the drainage recess without hindering the flow of water.

  The inside of the drainage recess has a capacity as a whole, and it is drained quickly with a downward slope, so that the sewage in the drainage recess is prevented from overflowing and the sewage crosses the side wall of the drainage recess and is on the bottom of the washing zone. It does not spread.

  Residues after cooking, for example, leftovers from cooking pots or leftovers, should be poured directly into the bottom of the drainage recess, which is lower than the bottom of the washing zone. There is no flow into the wash zone.

  In addition, by arranging the faucet fitting on the washing zone side, the position of the discharge pipe of the faucet fitting and the position of the drain outlet are far away, and the water discharged from the discharge outlet at the tip of the discharge pipe rebounds from the vicinity of the drain outlet. It is possible to prevent problems such as fouling. By each of the above actions, the washing zone can be made difficult to get dirty, and can always be kept clean and hygienic.

  Since the washing zone has neither a drain opening nor a lid that closes the drain opening, it is excellent in washing workability and easy to clean the washing place.

  Since the drainage port is located in the drainage recess at the side edge or corner of the sink, the storage space under the sink can be used effectively.

  As described in claim 2, it is preferable that the downward slope of the bottom surface of the washing zone is 1/100 to 1/25, and the downward slope of the drainage recess is 1/25 to 1/5.

  By setting the descending slope at the bottom of the washing zone to 1/100 or more, the water on the bottom of the washing zone can be quickly flowed down to the drainage recess without being retained, while the descending slope is 1/25. By setting it as the above, the inclination of the bottom face of a washing zone is not so tight, and washing | cleaning workability | operativity of foodstuffs, tableware, a pot, etc. can fully be ensured. Moreover, by setting the descending slope of the drainage recess to 1/25 to 1/5, the flow rate of the water after falling from the washing zone to the drainage recess can be increased and drained quickly.

  As described in claim 3, it is preferable that the area of the drainage recess in the sink is 10 to 20% of the total area of the sink. By making it 10% or more, it becomes easy to flow the residue after cooking directly into the drainage recess, and by making it 20% or less, the area of the washing zone can be sufficiently secured.

  As described in claim 4, it is desirable that the height difference between the edge of the bottom surface of the washing zone facing the drainage recess and the bottom surface of the drainage recess is at least 2 cm. By maintaining the height difference at least 2 cm or more, water can easily flow into the drainage recess, while water flowing in the drainage recess can be more reliably prevented from flowing into the washing zone.

  As described in claim 5, it is preferable that the drain outlet in the drain recess is located at a corner on the rear side of the sink. The storage space below the drainage zone can be used effectively by positioning the drainage outlet in the drainage recess at the corner on the back side of the sink.

  A scrap removing device according to claim 6 of the present invention is a scrap removing device attached to the sink according to claim 1, and includes a mesh cage installed at a drain outlet, and a part of the mesh cage. It is provided with the support | pillar provided and the scraping member detachably suspended by this support | pillar, It is characterized by the above-mentioned.

  According to the scrap removing device according to the sixth aspect, dust collected in the net cage installed at the drain outlet can be taken up immediately by holding the column with the support and is sanitary. Further, the scraping member can be removed from the support column, and the scraping member can be used to scrape dust accumulated in the net cage or scrape off vegetable scraps attached to the support column. A disposable filter may be detachably attached to the inside of the net cage. This filter can be removed from the mesh basket using a scraping member.

  As described above, in the sink according to the present invention, the drainage recess continuing from the bottom surface of the washing zone in the sink is disposed at the side end or corner in the sink, and the drainage opening is provided in the drainage recess, The entire bottom surface of the washing zone is directed toward the drainage recess, and the drainage recess is provided with a downward slope toward the drainage outlet, so that the washing place in the sink is not easily soiled and always kept clean. There is an effect that a hygienic sink can be obtained.

  In addition, there is no drainage outlet and its lid in the washing zone, so it can flow smoothly into the drainage recess without obstructing the flow of water in the washing zone, and it is easy to clean and easy to use while being excellent in washing workability. The effect is excellent.

  Furthermore, since the drainage port is positioned in the drainage recess at the side end or corner of the sink, the storage space under the sink can be effectively used.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a plan view of a sink 10 showing a first embodiment of the present invention, and FIG. 2 is a cross-sectional view of the sink 10 shown in FIG. As shown in these drawings, the sink 10 of the present embodiment has a groove bottom 14a at the side end in the horizontally long sink 12 formed on the top plate 11 more than the bottom surface 13a of the washing zone 13 in the sink 12. A lowered drainage groove (drainage recess) 14 is disposed, and a drainage port 15 is provided in the drainage groove 14. A faucet fitting 16 is attached to the rear of the sink 12 and is located in the center of the washing zone 13 in the width direction. Further, the drainage port 15 is located at the rear corner of the drainage groove 14 extending in the depth direction at the side end of the sink 12. In the plan view of FIG. 1, a cooking table and a gas table are sequentially arranged on the left side of the sink 12.

  The washing zone 13 is a zone that serves as a washing place for ingredients, tableware, pots, etc., and spills the ingredients such as spaghetti in the zone. The washing zone 13 occupies most of the width of the sink 12, and when the cross section of the bottom surface 13a is viewed from the front in the depth direction, the entire surface is a smooth surface as shown in FIG. The bottom surface 13a of the washing zone 13 has a gentle downward slope between 1/100 and 1/25 from the side end on the countertop side toward the drainage groove 14 on the opposite side.

  According to the level of dirt, the washing area 13 further includes an upstream area for food washing / boiled and spilled area A (area that controls a small amount of dirt), and a downstream area that is dishwashing / pan-washed area B (which controls stubborn dirt). (Area) can be used.

  The faucet fitting 16 located near the back of the sink 12 of the top plate 11 is located in the center of the washing area 13 in the width direction, and the tip of the water discharge pipe 17 reaches the center of the washing area 13 in the depth direction. It is possible to extend and discharge water from the discharge port 17a at the tip to the substantially central position of the washing zone 13. Further, the discharge pipe 17 can be swung as shown in FIG. Since the washing zone 13 has a downward slope toward the drainage groove 14, the water discharged from the outlet 17 a of the water discharge pipe 17 and used for the washing operation is a bottom surface of the gentle downward slope of the washing zone 13. It flows like a river toward the drainage groove 14 on the side end on 13a.

  On the other hand, the drainage groove 14 is a zone that collects wash water falling from the edge 13a 'of the washing zone 13 on the groove bottom 14a and drains it through the groove bottom 14a to the drain outlet 15 at the corner of the drainage groove 14. There is also a zone in which residues after eating, for example, leftovers such as pots and leftovers are thrown directly into the drainage groove 14 and collected in a scraper 20 to be described later at the drainage port 15. When the cross section of the groove bottom 14 a is viewed in the width direction of the sink 12, the drain groove 14 has a groove surface from the near side in the depth direction of the sink 12 toward the drain port 15 at the back corner as shown in FIG. 3. 14 a has a downward slope between 1/25 and 1/5, which is slightly larger than the bottom surface 13 a of the washing zone 13. As a result, the water that has fallen from the edge 13a 'of the bottom surface 13a of the washing zone 13 to the groove bottom 14a of the drainage groove 14 moves toward the drainage port 15 and is drained from the drainage port 15 to the drainage pipe 18 while increasing the flow velocity.

  When the cross section of the drainage groove 14 is viewed in the depth direction from the front side of the sink 12, the side walls 14b and 14b rise smoothly from the groove bottom 14a, and one side wall 14b is in the washing zone. 13 is smoothly connected to the edge 13 a ′ of the bottom surface 13 a, and the other side wall 14 b is smoothly connected to the edge 11 a of the top plate 11.

  The height difference between the edge portion 13a 'of the bottom surface 13a facing the drainage groove 14 and the groove bottom 14a of the drainage groove 14 in the washing zone 13 is secured at least 2 cm.

  The example of each dimensional relationship of the sink 10 having the above structure will be further described. When the sink 12 is a sink having a width × depth of 100 cm × 45 cm, the washing zone 13 has a width of 85 cm, from the top plate 11 to the bottom surface 13a. Is 18 cm at the left side furthest from the drainage groove 14, 20 cm at the right edge 13 a ′ desired by the drainage groove 14, the height difference between them is 2 cm, and the descending slope is 2/85 = 2. %. The drainage groove 14 has a width of 5 cm, the area of the drainage groove 14 occupying the sink 12 is 15% of the total area of the sink 12, and the depth of the groove bottom 14a is the farthest from the drainage port 15. The position is 4 cm, the position facing the drain port 15 is 6 cm, the height difference between them is 2 cm, and the descending slope is 2/30 = about 6.67%. The height difference between the edge 13a 'of the bottom surface 13a of the washing zone 13 and the groove bottom 14a of the drainage groove 14 is 4 cm to 6 cm.

  On the step portion 15 a of the drain port 15, a debris removal device 20 that captures the dust flowing in the drain groove 14 is installed. As shown in FIG. 4, the scrap removing tool 20 includes a tool main body 21 and a scraping member 22 that is detachably suspended from the tool main body 21. The former instrument body 21 includes a hemispherically recessed metal net cage 24 with a gutter 23 installed on the step portion 15 a of the drain outlet 15, and a support column 25 facing upward from the upper surface of the gutter 23 of the net cage 24. The engaging block 27 of the scraping member 22 is engaged with an engaging block 26 that also serves as a handle provided at the upper end of the support column 25.

  The scraping member 22 is provided with a circular scraping plate 29 at the lower end of the support column 28 and the engagement block 27 at the upper end of the support column 28, respectively, and protrudes from the engagement block 27 as shown in FIGS. The dovetail part 27a is inserted into the dovetail groove 26a on the engagement block 26 side from the upper part to the seating part 26b, and can be removably suspended only on the engagement block 26 upward.

  A trap portion 19 is provided between the drain port 15 and the drain pipe 18, and a headed cylindrical lid member 30 is placed on the inner cylinder portion 19 a of the trap portion 19 communicating with the drain pipe 18. By rotating the lid member 30, the plurality of locking projections 30 a on the side peripheral portion are engaged with or released from the locking projections 19 c on the inner surface of the outer cylinder portion 19 b of the trap portion 19. It can be done.

  Two rows of ridges 30b and 30b are erected on the upper surface of the lid member 30, and the scraping plate 29 of the scraping member 22 is inserted from above into the gap S between the ridges 30b and 30b. The engagement state between each locking projection piece 30a and the locking projection piece 19c on the outer cylinder portion 19b side of the trap portion 19 can be released.

  After the engagement state is released, the small hole 29a (see FIG. 6) provided in the scraping plate 29 of the scraping member 22 is fitted into the locking protrusion 30c on the side surface of the convex strip 30b on the lid member 30 side, and the lid The member 30 can be pulled up from the trap portion 19. Thereby, each cleaning of the cover member 30 and the trap part 19 can be performed. After cleaning, the cover member 30 can be attached to the trap portion 19 by using the scraping member 29 again.

  According to the sink 10 of this embodiment, since the drainage port 15 is located in the drainage groove 14 at the side end, the drainage port 15 does not need a lid for maintaining a horizontal plane, and the scrapper 20 is pulled up to easily remove the waste. Can be thrown away. Since the scrapper 20 has a handle, it is not necessary to use rubber gloves. Moreover, since the scrap removal tool 20 is installed in a place where the frequency of use is lowest, it does not interfere with the washing operation.

  Since the scraping member 22 can be used for scraping scraps and attaching / detaching the lid member 30 of the trap portion 19, it is convenient. When not in use, the scraping member 22 can be hung on the instrument body 21 of the scraper 20. It also saves you the trouble of searching.

  In general, tableware and the like are often washed after being soaked in a washing bowl. However, this washing bowl only has to be brought close to the drainage groove 14 side, and the washing bowl does not fall into the drainage groove 14. Even if there is a drain ditch 14, the washbasin can be used normally.

  Although not shown, a filter can be detachably attached to the inside of the net cage 24. In addition to using a petroleum product with a coarse mesh, this filter can be made of an environmentally friendly vegetable plastic or a natural material that can adsorb oil.

  According to the sink 10 of the present embodiment, the drainage groove 14 has a sufficient capacity and functions as a reservoir mass. In addition, the trap portion 19 directly below the drain port 15 can secure a capacity, and the drain pipe 18 extends directly from the trap portion 19 so that drainage can be performed quickly without resisting gravity. Therefore, it can be said that the structure is easy to drain.

  FIG. 8 shows another embodiment. The sink 40 shown in FIG. 8 has a smaller overall width than the sink 10 shown in FIG. 1, and thus the width of the sink 41 is also smaller than the sink 12 shown in FIG. Is.

  For this reason, the entire width of the sink 41 is used as the washing zone 42, and the area of the washing zone 42 is secured, while a drain outlet is provided at the corner of the sink 12, that is, the corner closer to the rear of the side opposite to the countertop. A drainage recess 43 with 15 is formed. The bottom surface 42 a of the washing zone 42 has a constant downward slope toward the drainage recess 43, and the bottom surface 43 a of the drainage recess 43 has a constant downward slope toward the drain port 15.

  The depth from the top plate 11 to the bottom surface 42a of the washing zone 42 of the sink 41 is 18cm at the position farthest from the drainage recess 43, 20cm at the edge 42a 'closest to the drainage recess 43, and the height difference between them is 2cm. It is. The depth from the top plate 11 to the bottom surface 43a of the drainage recess 43 is 24 cm at a position directly below the edge 42a ', 26 cm at the position facing the drainage port 15, and the height difference between them is 2 cm. The height difference between the edge 42a 'of the bottom surface 42a of the washing zone 42 and the bottom surface 43a of the drainage recess 43 just below it is 4 cm.
